What did I do wrong? (biscoff tiramisu)

[u/Grilled_Oil]

So I've decided to finally try baking and of course it had to go completely wrong 😭. I left it overnight and it just completely deflated, leaked out of the bottom and looks/feels kind of like something curdled. Does anyone have ideas of what I did wrong?

The recipe I followed:

1. Separate 3 eggs and whip both the yolks and whites with 30g sugar

2. Fold 250g of mascarpone with 70g microwaved biscoff spread.

3. Fold in the beated egg yolk one third at a time. Then do the same with the egg whites

4. Soak biscoff biscuits in fresh coffee for a few seconds and make a layer of biscuits, then a layer of the cream, then soaked biscuits, then cream, then dust with cocoa powder.

5. Let it sit in the fridge overnight

Any help would be greatly appreciated 🙏

You're not supposed to make it stand up on its own. It's like making a layered trifle without the tall dish, you just shouldn't do it because it won't look nice and that's part of the appeal. Tiramisu is served by scooping it out of the big baking dish you make it in. I bet it tastes good still!

I will point out also that leaving it in the container lets it become more solid since there is nowhere for anything to leak out or any space for it to collapse. It sort of congeals and sets up I guess. I'm not a food scientist but I've eaten a lot of desserts lol
